What is Biomechanics?:
BIOMECHANICS is the study of the scientific
principles which contribute to human movement.
BIOMECHANICS studies the internal forces
(generated by muscles, tendons) and the
external forces (gravity, resistance) acting on a
human body

Coaches need to understand:
“Players with sound biomechanics are able to perform skills efficiently, with minimum fatigue or injury”

The Central Theme of Biomechanics
|
| |
|
Balance and Stability
|
| |
What Is Balance?
Is the feeling of being in total control of the body without having to move or think about readjustments. (Centre of Gravity) |
 |
What is Stability?
Is the feeling of being firmly fixed in a strong position which is not likely to move or change (Stable Base)

Stability Principles
A body is balanced when its centre of gravity is vertically within its base of support
A body loses balance when its centre of gravity is vertically outside its
base of support
|
| |
| |
|
Static & Dynamic Balance
Balance can involve a fixed base (static balance),
or maintaining body control during movement (dynamic balance)
|
|
STABILITY – DYNAMIC BALANCE
|
|
|
Stability - Consequences
Balance is affected when any body part is moved away from the centre of gravity
When balance is lost or affected readjustments must occur
"ACTION Vs REACTION"
|
| |
|
Stability
A STABLE BASE enables FULL FORCE GENERATION
The bat starts to move FORWARD only after the front FOOT has made CONTACT with the GROUND
The legs remain BRACED to ensure maximum force generation
|
|
Stable Base
A stable base ensures :
- Eyes are still, so perception is enhanced
- Resistance to work the body levers against
- Body energy is transferred efficiently to the bat / ball
|
|
|
Dynamic Balance
Note the uncontrolled head position in this example, why?
Delivery stride forms a dynamic base of support – not aligning at target CAN be dangerous!
|
|
|
LEVER ALIGNMENT
To maximise POWER and CONTROL all body levers must move along the target line
“Direct the energy / core of the body at the target”
|
| |
Batting
- Step at target
- Rotate shoulders in direction of target
- Align front elbow with target
|
 |
Bowling
- Pump elbows up and down target line
- Keep ball in close to body
- Drag front elbow down target line
- Rotate shoulders vertically towards target
